In this research low density poly ethylene (LDPE) granules used as replacement for coarseaggregate for producing concrete cubes and cylinders has been investigated and reported. LDPE basedconcrete cubes and cylinders were cast manually and the strength of the test concrete in terms ofcompression and split tension were experimentally evaluated. It is found that the strength of plasticreplaced concrete in terms of compression and split tension can be comparable with the conventionalconcrete. The present study is aimed at concrete mix with partial replacement of coarse aggregate byLDPE granules (0, 10, 20 and 30) that will provide an advantage in reducing the dead weight ofstructure. This mix in the form of cubes and cylinders were subjected to compression and split tension toascertain the strength parameter. Hence the use of plastic granules in concrete making is not onlybeneficial but also helpful in disposal of plastic wastes.
